SPECIFICATION forming part of Letters Patent N0. 757,538, dated .April 19, 1904.

Application filed March 7, 1903 Serial No. 146,781. (No mcdei.)

- a imiter-box in which the saw-guidescan be turned so that the saw can produce an undercut.

In the accompanying drawings, Figure 1 is a plan view of my improved miter-box. Fig. 2 is a transverse central section. Fig. 3 is a partial elevation.

The platform 1 has feet 2 supporting it.

l A plate 3 is secured to the under face of the platform and has a rearward extension, to which is pivoted a horizontal bar 4, having its ends 5 turned up and each end provided with an opening. A segmental plate 6 is secured to the under face of the platform and has its outer edge provided with notches 7. A spring-plate 8 has a connection with the bar 4 and movable therewith and capable of v entering the notches 7 in the segmental plate,

thereby forming a connection between the bar 4 and platform.

The saw-guide comprises a horizontal bar 9 nd two upright-s 10, one at each end of the ar. tion with the upturned ends 5 of the bar 4; by the rivets 11, which permit the saw-guides to stand at an angle oblique to the platform'. Within each upright 10 is located a movable saw-guide l2, having a lengthwise slot 13 and an opening 1li for the saw-back. A cylindrical opening 15 is formed in each sawguide, and within the opening is located a lengthwise-movable stop V16, held in its adjusted position by a pin 17, passing through the upper end of the saw-guide and one of the holes 18 in the shank portion of the stop. From the bar 4 extends an arm 19, and from the rear saw-guide support 1() extends an arm 20, to which is pivoted a link 21, having a lengthwise slot 22, within which is located 'a clamping-bolt 23, serving to connect the link These uprights have a pivotal connec` with the arm 19. B v means of this adjustment the saw-guides 10 are moved on their pivotal connection with the bar 4 and held in any adjustment.

If a saw is employed having a thick back, the back is located in the openings in the sawguides and the guides can be raised in their supports to allow thematerial to be cut to be placed on the platform.

If a thin-back saw is used, the strips 16 are adjusted in the lengthwise direction of the saw-guides to-meet the requirements ofthe width of the saw.

By liberating the spring-bar from the notches in the segmental plate the bar supporting the saw-guide supports can be turned so that the saw can be set at different angles,

and as the adjustment for producing theV oblique cuts is carried by the bar 4 a combination'of cuts can be had.-

By having the stops 16 vertically adjustable in the saw-guides saws of diiferent widths can be used.

I claim as my invention- 1. Amiter-box comprising aplatform, a bar located beneath the platform having upturned endsy and having a pivotal connection With the platform, a saw-guide located beneath the bar 1 having uprights pivotally connected to the upturned ends, movable saw-guides located in the uprights,v a curved notched plate and a spring-plate connected to the bar and adapted to enter the notches. Y

2. A miter-b'ox comprising aplatform, abar located beneath the platform having upturned ends and having a pivotal connection with the platform, a saw-guide located beneath the bar having uprights pivotally connected to the upturned ends, movable saw-guides located in the uprights, a curved notched plate, a springplate connected to the bar and adapted to enter the notches, an arm extending from the bar and a slotted link forming a connection between the arm and one of the uprights.
